The authors describe a Wikipedia-based project designed for a graduate course introducing health economics to experienced healthcare professionals. The project allows such students to successfully write articles on niche topics in rapidly evolving health economics subspecialties. These students are given the opportunity to publish their completed projects in Wikipedia. Despite the lack of conventional classroom incentives, the authors have found that the students generally choose to enter their final projects into Wikipedia. The authors explore the motivators for this behavior from the perspective of human capital development and reflect on the implications for enhancing economics education. Finally, they comment more generally on the value of assignments within graduate education that allow adult students to determine their degree of effort and reward along the intensive margin.
